CUTTING AND SCORING ATTACHMENT.

Application l'ed May 3,

To all whom it may concern:

Be it known that I, HENRY DE SMITH, a citizen of the United States,residing at Rochester, in the county of Monroe and State of New York,have invented certain new and useful Improvements in Cutting and ScoringAttachments; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to improvements in cutting and scoring devices ofthe type disclosed in Letters Patent No. 865,020 granted September 3,1907, and which are used for cutting and scoring paperboard in themanufacture of boxes and other articles.

In this type of device there is employed a holder block, adapted fordetachable connection with the cutter-bar of the machine on which thedevice is used, a .cutter disc mounted in said block, and means foradjusting the cutter disc in the block Jfor the purpose of regulatingthe depth of cut to be made by it in the paperboard.

The main object of my present invention is to provide an improved mean-sfor eliecting the adjustment of the cutter disc and maintaining it inits adjusted position. Such means is illustrated in the accompanyingdrawings, in which- Figure 1 is a side view of a cutter and scorerconstructed in accordance with my invention, the same being shownattached to the supporting cutter-bar of the machine and in operativerelation to its co-acting bed-roll.

Fig. 2 is a side view of the device in section and elevation.

Fig. 3 is a sectional detail on the section line 33 of Fig. 2, and

Fig. 4 is a perspective view ot a clamp member for holding the cutterand its associated parts in adjusted position.

The cutter-bar 2 and the bed-roll 3 are of usual construction andarrangement as found in paperboard cutting and scoring machines now onthe market, the said cutter-bar being supported centrally above thebed-roll for the support of the cutters and the bed-roll being adaptedto carry the paperboard beneath said cutters to be cut land scored bythem.

The cutting and scories device embodyf 1922. Serial N10. 558,245.

ing my invention as here shown comprises a holder block 4 having meansat its upper end for adjustable connection with the cutter-bar 2 and inits lower portion having a vertically arranged open groove 5 to receivethe cutter disc 6 and certain of its associated supporting and adjustingparts. The cutter disc 5 is adapted to be supported in a manner topermit of its adjustment toward and from the bed-roll 3. To provide forthis, it is here sho-wn as journaled on an axle pin 6 moimted in thelower end of an adjustable carrier 7 and having its opposite endsengaging in elongated slots 8, 8, in the opposite side `walls 9, 9, ofthe holder block, the'said slots preferably being arranged in a verticalplane intersecting the axis of the bed-roll and constituting a guide forthe axle pin and cutter thereon during adjustment of the same towardsand from the bed-roll, as disclosed in the aforesaid patent.

The adjustable carrier 7 for the cutter is also located in the groove 5of the holder block and is bifurcated at its lower end to receive thecutter disc, as shown in Fig. 2. This carrier is yieldingly held in anormal raised position with the axle pin at the upper ends of the guideslots 8 by means of `a threaded pin 10, which is pivotally connected atits lower end with the carrier at 11 and at its upper end provided withan adjusting nut 12 resting upon the upper end of a coiled spring 13seated within an opening 14 in the holder block as shown. By turning thenut 12 up and down on the pin 10, the tension of the spring 13 will beadjusted to properly support the carrier 7.

As a means for eli'ecting a vertical adjustment of the carrier 7 andsupported cutter 6, an adjusting screw 15, having a milled operatinghead 16, is threaded into the front wall 01:' the holder block with itsinner end extending into the groove 5 of the latter and engaging withthe end wall of the car.- rier therein as shown. By turning thisadjusting screw inwardly against the engaging end of the carrier, itwill cause the latter, by reason of its contact with an inclined guidewall 17 at the upper side of the groove 5, to move downwardly andthereby lower the supported cutter disc towards the bedroll 3, thedirection of movement of the Cutter die@ being @Ontwlld by the amd@slots 8 as before described. If it is desired to raise the cutter disc,this may be effected by simply turning the screw 15 in the oppositedirection, as the carrier will be raised andl follow the screw by theaction of the spring llagainst the nut 12 on the pin 10.

After the cutter and its carrier have been properly adjusted by theaction of the screw 15, it is then necessary, in order to maintain suchadjustment, to fasten the screw aganist turning movement. This Iaccomplish in a simple and effective manner by' providing a clampmember' 20, having at one end an inwardly turned lip 21 for engagementwith the face of the holder block to' hold the meniber in spacedrelation thereto, and adjacent its other en'dhaving a threaded opening22 engaged by the screw 15. Intermediatel of its ends, said clamp memberis engaged by the head of a set screw Y23 which passes loose- 1y throughan opening 24' therein and engages the holder b-locl'r' within athreaded opening E25. By tightening up on the set 'screw 23, the clamp,through its threaded connection with the screw 15, is caused to clampand lock said screw against turning movement. By looseningthe set screwQ3, the clamp member isV thereby released from its' binding" engagementwith the adjusting screw 15 and permits of the latter being readilyturned to effect any desired adjust- 'nient of the cutter in the mannerdescribed.

YVhat I claim is 1. A ctting' or scoring attachment comprising a holderblock having a groove in its lower end the upper wall of whichconstitnte'sa guide wall, 'a cutter and a carrier therefor located insaid groove, a spring yieldingly holding the cutter `carrier in slidingcontact wthsad guide wall, an adjusting screw threaded into the' holderand 'operative to engage the cutter 'carrier and adjust the same withrespect to said guide wall, a clamp member held in spaced relation tothe Outer face 'of the holder and having a threaded opening engaged bythe v.adjusting screw, adjusting means yl `)o'sely engaging said clampmember to cause it to bin-d the adjusting screw and hold the latteragainst turning.

2. A cutting or scoring attachment comprising a holder block having agroove in its lower end the opposite side walls of which are providedwith elongated slots and the upper wall of which constitutes a guidewall, a cutter a carrier therefor located in said groove, an aXle pin onwhich the cutter is mounted having its ends slidably supported in saidelongated slots of the holder block walls and also having connectionwith the cutter carrier for movement therewith, an adjusting screwthreaded into the holder block and operative to engage the cuttercarrier and adjust the same with respect to said guide wall, a pinpivotally connected at one end with the cutter carrier, a springengaging said pin and yieldingly holding the carrier in sliding Contactwith both said guide wall and the end of the adjusting screw, and meansfor holding the adjusting' screw against turning.

8. A cutting or scoring attachment comprising a holder block having agroove in its lower end the opposite side walls 'of which 'are providedwith elongated slots and the upper wall of which constitutes a guidewall, a cutter and a carrier therefor located in said groove, an axlepin on which the cutter is mounted having its ends slidably supported insaidelongated slots of the holder block wallsr and also havingconnection with the cutter carrier for movement therewith, an adjustingscrew threaded into the holder block and operative to engage the cuttercarrier and adjust the same with respect to said guide wall, a pinpivotally connected at one end with the cutter carrier and 'having anadjusting nut thread-ed thereon, a

*spring engaging said nut `on the 'pin and yieldingly holding' thecarrier in sliding contact with both said guide wall and the end of theadjusting screw, and means for holding the adjusting screw againstturning.

In testimony whereof I affix my signature.

HENRY DE SMITH,
